Summary
You've lost focus. Ink wants to know why, and he's determined to get it out of you.
Edit: This started as just me wanting to write smut with Ink, and it turned into a damn love triangle between Reader, Ink and Error, complete with (maybe platonic) cameos from other Sansi.
Anyways, here's a whole porno with plot, if that's your thing XD

Summary
You had dealt with many things in your life. Fae, Supes, the Paranormal. Should be normal and easy for you, right? Wrong. When tragedy struck the Monster part of the city, there wasn't much else that could be done other than relocation. Guess who got the honor of being a host to some skeleton monsters? It wasn't Karen down the road, that's for sure. What do you get when you try to mix a human trying to keep secrets, and a bunch of suspicious skeleton monsters with mixed feelings? Trouble.

Summary
You are a street musician who can play the incredible but not enough well appreciated glockenspiel.
Life isn’t that bad especially after the monsters returned the city after being exiled in the exterior part of the country, it wasn’t pretty for the monsters, they basically lived in a mountain until they were helped to return human society by a child named Frisk that now works as a ambassador for monsters alongside with a carrier in politics just like Frisk’s father… Like father Like Son, after all you also chose your passion in life after admiring your father and his love for music.
Sans your friend for 2 years is acting weird after reciving the untimely unannounced visit from all his 'cousins' that looks similar to him ans his brother Papyrus.
Well, they are monsters and that's maybe normal for them... after all all the temmies and Froggits looks the same to you.You don't really care about it... except for the small but troublesome detail that Sans' family does hate you, they act as if you are disgusting and are trying to get you away from your friend... Why are those skeletons trying to kill you?

Summary
Les monstres ne sont pas exactement l'image que les humains s'étaient — pendant si longtemps — faite d'eux. Certains aspects pouvaient se rapprocher de la réalité, comme des dents pointues, des "déformations", des poils, des plumes, et cetera... Mais aucun livre d'histoires pour enfant n'aurait pu prévoir ce... caractère... si typique du peuple en question.
En effet. Ce n'est pas tous les jours qu'une nouvelle espèce intelligente apparait sur Terre. Et ce n'est pas non plus tous les jours qu'une nouvelle espèce intelligente apparue sur Terre possède une libido si débordante qu'elle se reflète jusqu'à dans leur manière-même de vivre.
Les humains sont intrigués.
Et un certain squelette aussi.

Time to get those bones. >;D
Seriously though, I can't believe I made it through this year to do this again! Now that I'm a little more organized, I can tell you that this is going to be a collection of hot garbage smut involving only Reader-insertXCannon pairings.
If that's your cup of tea, jump on in. A quick warning, as I forgot to mention, there's gonna be some dark smut fics this year. I'll mark them out at the beginning, so please, pay attention to the tags and the author's notes. Thanks ^^

So you got woken up in the middle of the night by your new neighbors... no biggie! You're sure they're just excited to be in a new (cheap) apartment. So you decide to introduce yourself to them when they get settled in.
But to your surprise, your new neighbor just so happens to be a skeleton!
"Oh!" You say, surprised by your neighbor's appearance, "Uh hey! Welcome to the unit, I'm your neighbor"
"oh! hey i'm sans" He smiles, lazily copying your initial reaction.You hold your hand out to shake, he looks at your hand for a moment before accepting it.
when all of a sudden...
PPPPPPRRRT!
Was that a... whoopie cushion in his hand?
